...-mesh proppant and 1-cp fluid dynamic viscosity. Then, parametric studies are conducted by varying the proppant size (20/40 mesh and 100 mesh) and fluid viscosity (5 mPa.s). The results show that the proppant size can significantly affect the fracturing performance. 20/40-mesh proppant has a severe...
